It'll be nice once the rumors fly around again, because some of the current rumors we have are pretty "yikes" in comparison. Like, some of the rumors are so obscure that it's pretty much, "That character could be anyone, and that leaker would be right".
I personally won't take leaks with anything more than a grain of salt unless I hear something about it myself or unless a more prominent leaker puts it out there. It's not that a Twitter leaker can't have legitimate information, but I don't see any reason to believe something that comes from a random account with no evidence showing reliability, as well as a rather obscure "prediction" that has little chance of being correct.
I also don't think there's ever been a leaker that starts with, "My English is bad!" that has turned out to be real in the end. Most correct leaks have been lists from a named source (very rarely anonymous posts) or flat out leaked like Ryu, Roy, ESRB, Gematsu, and Simon/Richter with the Castlevania Youtube screwup. In addition the whole, "I saw a model of a character" is not something I really believe either.
It's going to be a long wait, but I think the next big pick-up in speculation would be during the Hero mini-Direct. It could give us some direction going forward, like if it makes Mii Theory or breaks it. That is what I'm mainly looking for.
Plus, I always like trying out the new fighters obviously. However, we're running in circles in terms of arguments and I don't have much to come up with right now. O O F.
